(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. In, 1313.)

T 0 all whom it may concern:

Be it known that I, ALFRED FALLoT, a subject of the King of Prussia, and residing at Plauen, Germany, have invented certain new and useful Improvements in Rotary Printing Machines (for which I have filed applications in Germany, Dec. 22, 1916, and March 1, 1917 Switzerland, Dec. 17, 1917,

Patent Numbers 79,188 and 79,189; Austria,

Jan. 8, 1918; Hungary, Feb. 4, 1918, and Feb. 5, 1918; and Great Britain, Feb. 4, 1918, Patent Numbers, 113,274 and 142,504), of which the following is a specification.

My invention relates to rotary printing machines having a plurality of printing presses mounted in a horizontal row or series preferably with the folding devices systematically arranged between the said presses, and with the paper rolls on cars and in particular my invention mainly comprises new arrangements and means for supplying the paper rolls to the presses in a more ready and expedient manner than heretofore.

The object of my invention, therefore, is to supply the paper rolls to the printing presses in the shortest possible time, that is to say, when a new roll is being substituted for a spent one, the press is stopped only for a minute period of time not exceeding that required for pasting the two ends of the paper webs together, and the machine thus may be said to work continuously.

To this end the paper rolls are supplied to the printing machine by means of cars each preferably constructed and arranged to carry two rolls in line and to introduce same into the machine to the proper place with respect to the printing press, one after the other, so that when the second roll of the pair has been supplied, the spent first roll is outside and can be removed for the subsitution of a new (third) one. When the second roll is spent the car is returned so that the third roll assumes the place below the press, while the empty second roll is outside and can be replaced bv a new one. As will be understood the cars, one for each press, have a reciprocatory movement below the respective presses for supplying the paper rolls to the latter, and the press is only stopped for or during the time of pasting together the paper webs.

My invention is shown in the accompanying drawings wherein- Fig. 1 is a diagrammatic vertical section of the machine, the parts not required to illustrate the invention being omitted.

Fig. 2 a side elevation thereof.

Fig. 3 is a diagram of the folding apparatus arranged between or after each pair of printing presses and Fig. 4 is a further illustration showing more of the constructional details; while Fig. 5 is a sectional illustration of the j ournal supports for the printing rolls.

Supposing the machine has twelve printing presses 79 combined in a common framing a as usual, and the paper webs are supplied from paper rolls 7), I) carried on cars, one for each press and adapted to run on rails 03 in a direction rectangular to the framing a, as will be seen from Figs. 1 and 2. Each car or train of cars carries two rolls and in the construction shown each car or train comprises two single cars or units 0 and 0, Fig. 1, suitably connected.

In starting the machine the paper roll 5 furnishes the web e to its press As soon as the roll 7) is spent the press p is stopped and the car (train) is moved along in so that the unit 0 now stands outside of the frame a as shown by the dotted lines, in Fig. 1.

As soon as the roll 5 has been pasted to the web, the press is started again. During the operation of the press a new roll of paper is substituted for the empty roll on the outside car 0 shown in the dotted lines and when the roll 6 is spent, the car 0 is returned to its original position so that the new roll thereon comes under the press 79, while the now empty car 0 will be outside of the frame ready for the reception of a fresh roll.

The short movement of the car and the pasting together require only a fraction of a minute so that the operation of the press is interrupted only for a minimum of time.

The car or car train 0 c is automatically moved. The means for moving the cars preferably. consists of a toothed rack 7 provided on the bottom of the car and in engagement with a toothed wheel or pinion g on a driving shaft it below the floor. Said driving shaft extends from one end to the other of the machine, and thus furnishes power to all of the twelve driving agents 7, g, of the The curved linesv in Fig. 3 show the possible connection of the presses in groups with the folding apparatus. The full drawn curved lines indicate the co-operation of all six folding apparatus each connected with two presses, whereas the dotted lines indicate the co-operation of but four folding apparatus (I, II, IV, V) each connected with three presses and the dash-ancLdot-lines indicate the co-operation of three foldin apparatus only (I, III, V), each connectec with four printing presses.

If the machine has six motors m inthe first case with six groups of presses all the six motors will be in action, in the second case with four groups two motors and in the third case with three groups three motors will be at rest.

As regards the printed matterthe machine is capable of producing with the different groups of presses, in the first case (six groups) 4:, 6, 8 to 16 pages of work in the second case (four groups) 12, 1a to 24; pages of work, and in the last case (three groups) 16 to 352 pages of work can be turned out. Besides if only two folding apparatus, each for six presses,are employed, 24 to 48 pages of work can be printed. This is a remark able progress since the old machines cannot turn out anything like it.

In the construction shown in Fig. 4 the main driving shaft comprises a number of single short shafts is interconnected by means of clutches Z to allow of dividing the shaft into single driving shaft sections of the required length, in conformity with the working motors.

Preferably, the motors m are located below the folding apparatus as shown in Fig. 4:. Each motor actuates the driving means of the folding apparatus, and at the same time each motor is the driving source of that number of printing presses which are connected therewith by means of clutches Z. As a separate motor is employed. in connection with each folding apparatus the machlne can always be fully utilized, that is to say, a maximum production is thereby ensured.

In Fig. 5 the particular journal support of the two rollsn and 0 of the printing press is shown. The said rolls are supported in the two walls a a of the frame by means of free journals 9 detachably inserted in holes of the walls from outside and secured in their position by means of screw-bolts r. The inner or free'ends of said journals carry the rolls with the aid. of ball bearings s and the longitudinal bores z? in the journal's serve as a means for li'ibricating the ball bearings.

What I claim is:

1. In a rotary printing machine the combination with a plurality of printing presses of a plurality of movable supports adapted to carry more than one paper roll, and means for imparting a reciprocatory movement to the said supports.

2.111 a rotary printing machine the combination with a plurality of printing presses,

of a plurality of movable supports adapted to carry at least two-paper rollsarranged in axial line with each other and means for reciprocating the said supports so as to bring either paper roll in position under the corresponding printing press.

3. In a rotary printing machine the combination with a plurality of printing presses, of a plurality of movable supports, each adapted to carry at least two paper rolls arranged in axial line with each other, means for reciprocating the said supports to bring either paper roll in position under the corresponding printing press and an automatic drive for actuating said means.

at. In a rotary printing machine the combination with a plurality of printing presses of a corresponding plurality of movable supports adapted to each carry at least two paper rolls arranged in axial line with each other, a toothed rack provided on the underside of each support, a driving pinion in engagement with each rack, and means for actuating the said pi'nions'to impart movement to the said supports. y y

5. In a rotary printing machine the combination with a plurality of printing presses, a common frame therefor, of a corresponding plurality of movable supports each adapted to carry at least two paper rolls ar ranged in axial line with each other, means for reciprocating the said supports to bring either paper roll into position under its printing press, an automatic drive for actuating said means,and a means to connect and disconnect at will the drive in connection with each support.

In testimony whereof I have afiixed my signature in presence of two witnesses.
